The eggs develop in water, and hatch, releasing '''coracidium'''. These are ingested by copepods, and the coracidium develop into '''procercoids'''. The copepod is then ingested by freshwater fish. These procercoids develop into '''plerocercoid'''. The infected fish are then ingested by a definitive host. | The eggs develop in water, and hatch, releasing '''coracidium'''.
